Electrical connector

Abstract

An electrical connector includes a housing and a fitting held by the housing, wherein the fitting is a reinforcement fitting or a shield fitting and includes: a mounting portion; a first wall which is provided so as to protrude in a first direction orthogonal to a mounting surface; and a second wall which forms an exposed surface that does not come into contact with the housing, the mounting surface of the mounting portion and the exposed surface of the second wall are to be plated after insert molding, and a first thickness of a plated portion having been plated on the mounting surface is greater than a second thickness of a plated portion having been plated on the exposed surface of the second wall.

What is claimed is: 
     
         1 . An electrical connector comprising:
 a housing including a lengthwise direction, a crosswise direction, and a height direction which are mutually orthogonal; and   a fitting held by the housing;   wherein the fitting is a reinforcement fitting or a shield fitting which is integrally molded with the housing by insert molding, which is made of a conductive thin plate-shaped base material held by the housing, and of which surface is to be partially plated after the insert molding,   the fitting includes: a mounting portion; a first wall; and a second wall; the mounting portion including a mounting surface which is to be mounted to a mounted object; the first wall being provided so as to protrude in a first direction orthogonal to the mounting surface, and the second wall being provided at a distal-side end to the mounting portion in the first wall in the first direction and forming an exposed surface being spaced apart from the mounting surface in the first direction and not coming into contact with the housing, and   a first thickness of a plated portion on the mounting surface is greater than a second thickness of a plated portion on the exposed surface of the second wall.   
     
     
         2 . The electrical connector according to  claim 1 , wherein the first wall further includes a wall surface which is provided in a second direction that is orthogonal to the first direction and which includes a contact surface that comes into contact with a part of the housing, and a thickness of a plated portion to on the wall surface after the insert molding is 0. 
     
     
         3 . The electrical connector according to  claim 1 , wherein the fitting includes a mounting-side fitting portion that includes the mounting portion and an exposed-side fitting portion that includes the second wall, and the mounting-side fitting portion and the exposed-side fitting portion are integrally provided with each other or separately provided from each other. 
     
     
         4 . The electrical connector according to  claim 1 , wherein the plating is performed by gold plating. 
     
     
         5 . The electrical connector according to  claim 1 , wherein the electrical connector comprises a receptacle connector, the receptacle connector includes the housing and the fitting held by the housing,
 the housing includes: a bottom wall; a protruding wall; a peripheral wall; and a fitting depression; the protruding wall being arranged on a mounted portion of the mounted object, the protruding wall protruding in a height direction of the housing from the bottom wall, the peripheral wall including a longitudinal wall and a short-side wall which are provided at an interval on an outer periphery of the protruding wall, and the fitting depression being provided between the protruding wall and the peripheral wall, and   the fitting includes a receptacle terminal, the receptacle terminal includes: the mounting portion; the first wall; the second wall; a third wall; a fourth wall; and a fifth wall; the first wall bending in a first height direction of the housing from the mounting portion and extending, the second wall bending in a second height direction on an opposite side to the first height direction from a connecting part with the first wall, the third wall extending in the second height direction from a connecting part with the second wall and opposing the first wall, the fourth wall bending toward a center of the receptacle connector from a connecting part with the third wall and extending, and the fifth wall bending in the first height direction from a connecting part with the fourth wall and extending and being configured to elastically come into contact with a counterpart terminal, and the fitting is held by the housing since the longitudinal wall of the peripheral wall of the housing is provided in an inner area surrounded by the first wall, the second wall, and the third wall.   
     
     
         6 . The electrical connector according to  claim 1 , wherein the electrical connector comprises a plug connector, the plug connector includes the housing and the fitting held by the housing,
 the housing includes: a bottom wall; a peripheral wall; and a fitting depression; the bottom wall being arranged on a mounted portion of the mounted object, the peripheral wall protruding in a height direction of the housing from the bottom wall and including a longitudinal wall and a short-side wall, and the fitting depression being provided on an inner peripheral side of the peripheral wall, and   the fitting includes: a plug terminal; the first wall; the second wall; and a third wall; the plug terminal including the mounting portion, the first wall bending in a first height direction of the housing from the mounting portion and extending, the second wall bending in the crosswise direction of the housing from a connecting part with the first wall and extending, and the third wall extending in a second height direction on an opposite side to the first height direction from a connecting part with the second wall and opposing the first wall, and the fitting is held by the housing since the longitudinal wall of the peripheral wall of the housing is provided in an inner area surrounded by the first wall, the second wall, and the third wall.   
     
     
         7 . The electrical connector according to  claim 1 , wherein the fitting includes the reinforcement fitting and a terminal.
